Hello, I just had a few questions about a black light that I bought: https://www.lowes.com/pd/Scorpion-Master-Mini-Flashlight-LED-Miniature-Flashlight-Battery-Included/3182999. It actually has a peak wavelength of 390 nm, and I was wondering if this thing had any chance of fading color off of shirts made from natural fibers (cotton, wool, etc.). I understand that the type of dye that was used is also important, but I do not know. 2.) If it does have that ability, I was wondering if anyone could explain why and how this particular flashlight has that capability. 3.) Is HDPE naturally resistant to this type of UV? Thank you and I look forward to your responses.
